But simply a 2D TVC airframe testbed.
We know of the existence of a 2D WS-15 J-20 testbed if you insist that it has to be the WS-15, but for general developmental testing a J-35/A would suffice I reckon.

Well, not by direct evidence.We know?
Another interesting tidbits I heard. Supposedly the following engine variants do exist and are for the J-20:
WS-10CXX
No TVC WS-15
2D TVC WS-15
3D TVC WS-15
Well, not by direct evidence.
From some time ago:
I don't see why it's out of the realm of possibility. It may not get mass-produced, but for R&D purposes it absolutely makes sense to have them.
